I think I'll wait until next Christmas
to purchase a new 4K UHD TV. By then all of the specs should be uniform, standardized and available in most of the major brands, including the long awaited UHD disc players. Besides, I just purchased my 60" PLASMA last year. And YES, I'll be upgrading to a 65" - 70" 4K UHD TV. Hopefully OLED
will be widely available then, too ! .
